FOLDABLE COMB.

Foldable combs have become known the elements of which are connected byhinges, said elements, if the comb is unfolded, being stiffened in thisposition, by means of a slide pushed over the back of the comb at thejoint. These combs present the il'lCOnveniences, that the hairs arecaught in the hinges which are open on the surface of the comb, that thehinges are foldable only in one direction and are easily broken out ofthe comb if accidentally the comb is folded in the wrong direction, andthat further the slides are too short and too narrow and con sequentlydo not sufliciently stiffen the comb. The hingeson the outer side of thecomb do not improve the appearance of the comb.

The foldable comb according to this invention is free from theinconveniences mentioned, and, in the position of use, it is stifienedby a slide in such a manner that it is even more resistant than anordinary comb.

According to the invention the comb has a double hinge at the jointbetween its two elements which double hinge is sunk into the comb back.The slide is long and ornamented and it is guided in longitudinaldirection by means of a guide rib in a groove cut into the surface ofthe comb back. The sunk double-hinge permits of folding the comb toeither side, any breaking of the elements at the joint being avoided.The slide can be pushed over the joint so that it covers the same and itis impossible that hair be caught in the hinge if the comb is used.

Application filed June 21, 1926, Serial No. 117,553, and in GermanyNovember 21, 1925.

An embodiment of-the invention is shown, by way of example, in the.accompanying drawing in which Fig. 1 shows the unfolded comb in thepositionof use in elevation.

Fig. 2 is a top plan view of Fig. 1.

Fig. 3 shows in elevation the comb folded.

Fig. 4 is a plan View of Fig. 3.

Fig. 5 is a cross section of the comb in the position of use.

Fig. 6 shows in end elevation the joint between the two elements of thefolded comb.

The elements a, b of the comb are connected with one another by a doublehinge 0 sunk into the comb back so that the comb can be folded in bothdirections. A slide d of U-shaped vertical section is slidably mountedon the comb back and guided by means of a guide rib e in a groove f cutinto one surface of the comb back. The slide (Z serves to stifien thecomb in the position of use and it covers the sunk double hinge c.

I claim A foldingicomb comprising in combination with the two halves, adouble hinge connecting with one another said two combhalves and sunkinto the comb back which has a longitudinal groove in one of itssurfaces, a slide of U-shaped section shiftably mounted on said combback, and a rib on the inner surface of said slide and engaging withsaid groove in the comb back.

In testimony whereof I affix signature.
